Present invention have the advantage that and utilize SNMP sub agent plug-in method to be deployed to cloud device, be on the one hand responsible for and throw
The proprietary protocol communication of shadow instrument, can change the detection project corresponding to OID by proprietary protocol communication, on the other hand for
Snmp protocol is packaged into publicly-owned agreement, and interacts with common support platform, the problem efficiently solving protocol processes, and real
Existing cross-platform characteristic so that the method is compatible strong and is more widely applied.
Accompanying drawing explanation
The present invention is further illustrated the most in conjunction with the embodiments.
Fig. 1 is the execution flow chart of a kind of projector universal monitor method based on SNMP of the present invention.
Fig. 2 is that the device of a kind of projector universal monitor method based on SNMP of the present invention disposes block diagram.
Detailed description of the invention
As described in Figure 1, a kind of projector universal monitor method based on SNMP, common support platform, cloud device need to be provided
And projector, described projector carries out data interaction by serial ports and cloud device, and described cloud device leads to common support platform
Cross network to connect, and interacted with common support platform by snmp protocol, described cloud device be Windows operating system,
(SuSE) Linux OS or Mac OS operating system, described method comprises the steps:
Step 1, in snmp protocol self-defined one group of OID, identify each detection project for unique, described OID includes father
Node, child node, the second child node and the 3rd child node；
Step 2, creative management information bank mib file, definition detection project corresponding to OID so that described detection project
Process inquiry can be managed and arrange；
Step 3, create the dynamic base of projector accessed, according to described mib file by the detection project of projector and OID
Carry out one_to_one corresponding so that all corresponding specific OID of each detection project, described detection project includes that vendor name, bulb are transported
Row time, lamp lumen value, fan-status, device temperature, nuclear core sheet warning information, bulb warning information, start shooting, shut down and
Duty, described duty is included in line states, broken string state and malfunction；
Step 4, described common support platform are according to projector detection purpose OID edit instruction, and are sent to cloud device,
It is transmitted to projector by cloud device；
Step 5, projector carry out corresponding operating according to the instruction received, and execution result is sent to common support puts down
Platform, described instruction includes control instruction and query statement.
Below in conjunction with a specific embodiment, the present invention will be further described:
Refer to Fig. 1 and Fig. 2, a kind of projector universal monitor method based on SNMP of the present invention, common support need to be provided
Platform, cloud device and projector, described projector carries out data interaction by serial ports and cloud device, and described cloud device is responsible for throwing
Shadow instrument data acquisition, can be Windows operating system, (SuSE) Linux OS or Mac OS operating system, described cloud device with
Common support platform is connected by network, and is interacted with common support platform by snmp protocol；
Self-defined one group of OID in snmp protocol, identifies each detection project for unique, and described OID includes father node, son
Node, the second child node and the 3rd child node, as shown in table 1:
Table 1
Creative management information bank mib file, definition detection project corresponding to OID so that described detection project can be by
Managing process inquiry and setting, created the dynamic base of the projector accessed, carried out the detection project of projector by described OID
Redefine so that all corresponding specific OID of each detection project, described detection project include vendor name, bulb run the time,
Lamp lumen value, fan-status, device temperature, nuclear core sheet warning information, bulb warning information, shape of starting shooting, shut down and work
State, described duty is included in line states, broken string state and malfunction, the most as shown in table 2:
Table 2
Described common support platform is according to projector detection purpose OID edit instruction, and is sent to cloud device, cloud fill
Putting and be transmitted to projector, described instruction includes control instruction and query statement, and query statement is for query warning information and looks into
Asking status information, control instruction arranges equipment for control, such as, controls device power-up or shutdown；Projector is according to receiving
Instruction carry out corresponding operating, and execution result is sent to common support platform.
Such as, in one embodiment, cloud device uses (SuSE) Linux OS, projector serial communication, and joins as follows
Put:
First, serial ports environmental variable is set, such as projector is connected on/dev/ttyUSB0 equipment under, then revise snmpd
Initialization files, editor/etc/init.d/snmpd file,
Add under export PATH=/sbin:/usr/sbin:/bin:/usr/bin row as descending:
Export PROJECTOR_SERIAL_PORT=/dev/ttyUSB0；
Secondly, add drop shadow instrument equipment mib file, revises snmp configuration file, editor/etc/snmp/snmp.conf literary composition
Part, adds as descending at last row:
If mib file leaves in/opt/PROJECTOR.MIB catalogue under,
Add mibs+/opt/PROJECTOR.MIB；
Again, revise snmpd configuration file, editor/etc/snmp/snmpd.conf file, add as follows at last row
OK:
If so file leaves in/opt/projector_abc.so catalogue under,
Add dlmod projector/opt/projector_abc.so；
Wherein dlmod parameter 1 is module name, and parameter 2 is the absolute path of dynamic base, it should be noted that parameter 1 is got the bid
Bright module name needs to name consistent with the initial function in module source code.
After snmpd has configured, restart snmpd service, as a example by obtaining duty functional test: use
Snmpwalk instrument is tested, and is the test entitled localhost of main frame in cloud device the machine, and input is to issue orders:
>snmpwalk-v2c-c pulic localhost.1.3.6.1.4.1.84000.1.3.9
If returning
XH-PROJECTOR-MIB::workStatus.0=INTEGER:online (0)；
Then explanation projector is in line states.
The present invention, by the unified publicly-owned agreement of projector, efficiently solves different projector agreement incompatible and different
The problem that operating system is incompatible, uses SNMP sub agent plug-in method to make various projector possess consistent access platform side
Formula, improves versatility and compatibility.
Although the foregoing describing the detailed description of the invention of the present invention, but those familiar with the art should managing
Solving, our described specific embodiment is merely exemplary rather than for the restriction to the scope of the present invention, is familiar with this
The technical staff in field, in the equivalent modification made according to the spirit of the present invention and change, should be contained the present invention's
In scope of the claimed protection.
